I want to scale the image I am including up. However, when I attempt to put anything in the [] field in \includegraphics[]{}, an error is thrown. However, it works with just \includegraphics{}. Can anyone provide a solution?

That is,

 \section*{Method}
\includegraphics[scale=0.5cm]{burnsideTri.png}


why is an error thrown here and not when it is just

\includegraphics{burnsideTri.png}

• Welcome to TeX.SX! Please reduce your code to the very minimum. We do not want to debug that many lines of code. Thanks you. – LaRiFaRi Dec 10 '14 at 6:48
• All of the code might be relevant. Hence why it is included. I edited the post for further clarity. – Ozera Dec 10 '14 at 6:53
• Might be, but actually it isn't. When deleting all of the rest, you will get the same error. Please do that work first, before asking something. In most cases, you will find the error yourself. – LaRiFaRi Dec 10 '14 at 6:54
• There. The post was further edited for clarity. No more may be deleted. I assure you that I have attempted to find the error myself before posting. – Ozera Dec 10 '14 at 6:59
• Sorry, but deleting the line \title{hello world \LaTeX} does change your problem? And the next line, and the next line...? This is by far not an MWE. – LaRiFaRi Dec 10 '14 at 7:03

The command to scale an image is \includegraphics[scale=0.5]{burnsideTri.png} (not 0.5cm). If you want to give a certain width, it would be width=0.5cm.

You should load graphicx instead of graphics as the prior is much more modern (and I never used the latter, so maybe the scaling will not work, I dunno).

Just in order to show you, what an MWE is.

That's how your question looks without all the noise:
